...give us a click at 120bpm for sixteen bars, let us get comfortable, then drop it out of the cans for four bars. If we came out the end of that still in time with the click he'd bump that up to eight bars. Then sixteen. Then thirty-two...
I love this exercise! A definite stabilizer.
BTW, some reality...
In a non-click environment, the time is simply there for a song. Grooves are tempo based, and grooves affect the song . Everyone has to do their part to keep the song alive and in the groove that fits the song. It is a constant and dynamic interaction between the musicians that not only set the tempo but keep the groove alive. Anything else is simply ego! The best time-keeping musician keeps the tempo solid for everyone else (or the song-writer if the song isn't rehearsed). Everyone looks to him/her for that. (in a perfect world all have equally perfect timing)
In a click environment, again, the time is simply there for a song. Everyone has to do their part to keep the song alive and in the groove that fits the song. It is a constant and dynamic interaction between the musicians that has to work with the tempo set by the click track. It is all members responsibility to keep the groove alive within that time. (if the groove doesn't fit the song then maybe the wrong temo was set)
In both cases, all are responsible for keeping the time and the groove. Depending on the style of music or the group of people, there may be more leeway for one instrument or the other, but THE SONG is really what is important. If everyone doesn't do their part, there is no groove and therefore no song.
It is a GROUP EFFORT! But, no matter what, being able to play in time with each other and a click is a requirement to be an EFFECTIVE musician of any instrument.
Now, do we bother tuning our instruments too?
